Label markings
- Bosch number: 0281014408 (0 281 014 408)
- Audi number: 4L0910401T (4L0 910 401 T)
- ECU type: Bosch EDC16CP34
Vehicle compatibility
The label decides, not the model year: the Bosch number 0281014408 and the Audi number 4L0910401T must be the same as on your ECU. If your Q7 version is not mentioned in the description, the unit may still fit. Watch out for similar numbers – 0281014407 (4L0910401S) has different software and is not a replacement, and Q7s with EDC17 (e.g. 0281015868) use a different ECU type.
Preparation and installation
On the EDC16CP34, disabling the immobiliser has no side effects – there is no message on the instrument cluster and no stored fault, and the engine starts straight after installation. You can also choose data cloning from your old ECU (included in the price) and paid services: DPF OFF, EGR OFF, FLAPS OFF and chip tuning.
Symptoms of a failed ECU in the Q7
In the Q7 3.0 TDI the ECU sits under the scuttle panel; when the drains block, water collects there. The most common symptoms:
- no communication with the ECU during diagnostics
- CAN bus faults and errors in several modules at once
- the radiator fans run constantly with the ignition on
These symptoms can also have another source (power supply, wiring, battery) – start with diagnostics. Details in the article: water damage to the Audi Q7 3.0 TDI ECU (EDC16CP34).
